AWNING.

SPECIFICATION forming part of Letters Patent No. 741,162, dated October 13, 19103.

Application filed September 5, 1902. Serial No. 122,210. (No model.)

To a/ZZ whom, it may concern,.-

Beit known that we, HERMANN OLTMANNS and CHARLES J. SCHMIDT, citizens of the United States,residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Awnings; and we do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in awnings of that kind employed on store-fronts where mechanism is used to operate the same.

The object of the invention is to provide an improved gear arrangement for operating the awning.

A further object is to simplify the construction of some of the parts of the awning in order that the rods of such awning may be easily changed in length to suit the desires of the user Without the usual expense incurred in such changes.

The above objects will be understood in the following specification, aided by the accompanying drawings, in which-v Figure 1 is an end View of an awning,show ing our invention embodied therein. Fig. 2 is a side view of our improved gear, showing an adjustable pin for locking the gear-wheels against movement. Fig. 3 is a plan view of a portion of a bracket shown in Fig. 2 with the hub of a gear-wheel projecting up through it and showing a locking-pin for engaging said wheel. Fig. 4L is a top view of one of the gear-wheels, showing a series of radiating ribs or arms between which the pin above mentioned is intended to drop. Fig. 5 is a longitudinal section of a bifurcated fitting for the end ofrcertain of the arms of the awning. Fig. 6 is a perspective View of a fitting also for certain of the rods.. Fig. 7 is a side view of a modified form of locking-pin as a substitute for that shown in Fig. 2. v

In Fig. l, A represents the shaft which carries the awning-roller, about which is wound the canvas B. Such shaft carries a gearwheel C, with which meshes a similar gear D. This latter gear is carried on a vertical shaft E, having bearings in an arm F, secured to the building, and in bracket G, which forms a support for the gear-wheels which operate the awning. One of these gears is indicated at I-I, being secured to the lower end of the said shaft E, while the other gear, I, is carried on a horizontal shaft J. The bracket G, mentioned above, consists of a horizontal limb having an upturned end at (G and a downturned end G2, as shown. 'Ihe said upturned portion is bolted to the building or other support, while the downturned end forms a bearing for the outer crank end of the shaft J, as shown. A supporting-bracket, comprising a horizontal limb G3, the vertical limb G4, and the angle-limb G5, is placed under the limb G and secured thereto bya bolt g and when secured to the building forms a very strong carrier for the gears, as may be seen. Upon the top of the limb G is a boss K, having a vertical bore entirel)7 through it and the said limb, and in this is inserted a pin L, as shown, which is designed to form a lock for the gear H to prevent the awning from lowering and for sustaining the same in whatever position it may be desired to place it. In order to accomplish this, we provide a peculiar form of wheel, which is illustrated in Fig. 4. It has a series of ribs 7i radiating from its hub i, and these project above the body of the wheel, and in addition thereto the said wheel-body is hollowed out between the ribs, and into these the pin L is intended to be inserted and there held by gravity or by a spring, as shown in Fig. 7. Said pin is provided with a lug M at diametrically opposite sides, which enter notches in the top of the boss K. When the pin is raised and turned so as to place the lugs M upon the top of the boss, it is kept out of engagement with the gear. Fig. 3 shows atop viewoi:` the limb G, showing the hub of the gear I-I and also showing the boss K and its pin. In Fig. 7 the pin is provided with a collar N, upon which bears a spring O, whose upper end bears against a cap P, screwed upon the top of the boss. In this Mway the pin is kept positively in engagement with the socket of the gear.

Now we show in Figs. 5 and 6 fittings for the ends of the horizontal bars Q, Fig. 1, said bars serving to support the canvas in the usual manner. In the building is the customary pin R, to which the awning-bars Q are pivotally attached. In ordinary practice the said bars Q if too long must be cut oft' and a new end formed ICO thereon for attaching again to the said pin R; but we in our construction have succeeded in doing away with this expensive and unsatisfactory method by providing the fitting shown in Fig. 5. This consists of a bifurcated portion S, having a hollow stem T. The two ears of the portion S are provided with holes, through which a bolt is pushed for pivotally securing it to the pin R. The end of the bar Q is merely pushed into the stem T and slightly headed with a hammer and the job is complete as to this portion. of the awning. At the forward end of the bar Q is asecond fitting, (shown in Fig. 6,) which comprises an L-shaped limb U, in which lies the wooden bar V, to which the canvas of the awning is tacked. Projecting rearward from this limbis a tubular stem W,into which is pushed the forward end of the bar Q. Said bar is headed in the same manner as before described,and the fitting is held securely against movement. Now if it is desired to shorten lthe bar Q it is cut at the desired length and the short piece pulled out through the portion S or W, as the case may be.. The end of the bar is then inserted and again headed. It Will thus be seen that a convenient device is provided and by which the work and eX- pense usually necessaryin fitting awnings are avoided.

Having thus described our invention, we claim- 1. In an awning, the combination of the bracket G5, G4, G5, the portion G secured thereto as shown and having the upturned and downturned extension G and G2, the horizontal shaft J carried in the portion G4 and the extension G2, a vertical shaftE journaled in the portion G, the gear-wheel H on the lower end thereof, a pinion on the horizontal shaft adjacent to the bracket G3, G4,

G5, a series of ribs h in the top of the gear H and a pin L in the portion G adapted to enter between said ribs all as set forth, and for the purposes described.

2. In an awning-gear, the frame compris.- inga horizontal limb G, the upturned portion G at one end for attachment to the building, A

the downtured portion G2 atthe other end for constituting a bearing for the operating-shaft, the support G3, G4, G5 secured to the frame G, G', G2 as shown and described, the operating-shaft J carried in the portion G2 at one end and in the support G5, G4, G5 at the other, a gear I on said shaft J adjacent to the said support, a gear H meshing with such gear I, a shaft E carrying the latter gear, there being depressions in the said gear H substantially as described and shown, the boss K on the top of the limb G, the pin L passing through said boss and the limb in a vertical direction and adapted to enter the depressions of the gear H, all being arranged substantially as set forth.

3. In an awning, the combination with the roller and operating mechanism therefor, ot' a supporting-rod for carrying the lower part of the canvas, the Lshaped tting at right angles to the said rod and a hollow stem thereon for receiving the end of the rod as described, and a tting at the opposite end of the rod consisting of the bifurcated portion S having a hollow stem T for receiving the opposite end of the rod as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
